Obersaxen
The Obersaxen plateau first appears in historic records in 765, as Supersaxa, when Bishop Tello gave his farms and meadows there to Disentis Abbey. In 806 it became an Imperial Estate, which it remained until 956 when Emperor Otto I donated Supersaxa village and the village church back to the Bishop of Chur. In 1227 it was mentioned as Ubersahse.

The current settlement was founded in the thirteenth century, when a group of German-speaking Walser settled the plateau. Right in the heart of the mainly Romansh-speaking Surselva (which encompasses the valley of the Vorderrhein, along with all of its side valleys, among others the Val Lumnezia), Obersaxen is an island of German-speakers.

Mundaun
Mundaun was formed on 1 January 2009 through the merger of Flond and Surcuolm.
